A friend posted "the most brilliant company logo" in her opinion and it was a priapic chicken for Dirty Bird fried chicken. The logo features small d and b with an arch over the vertical elements (the priapic part) and on the arch a beak and cockscomb (the chicken part). (Go search it if you care.)
I've had this listed down for Word of the Day for such a long time I don't recall where I first got this word. It's a useful word to have; I like sounding intellectual when I have to insult someone--actually, is "prick" a contractions of priapic? Hm.
